Title: Volume measuring device
Inventor: TANAKA HARUTO
IPC: G01F17/00
Filed: 1994-05-18
Abstract: PURPOSE:To enable volume measurements which are accurate and of excellent reliability by disposing a first microphone in such a way that its vibrating surface is parallel to a pressure direct wave produced at a loudspeaker. CONSTITUTION:A first microphone 6 is mounted on the side of a main tank 4 in such a way that its vibrating surface 6A is parallel to the direction of flow of a pressure direct wave W produced when a loudspeaker 1 is driven. The direct wave W produced from the loudspeaker 1 is therefore not received directly by the vibrating surface 6A, and so the pressure on the vibrating surface 6A is not increased or decreased by the direct wave W. Thus micro pressure signals can be obtained which are equivalent to those obtained when microphones 6 are arranged on both right and left sides and on the back.

Title: Silver halide photographic sensitive material
Inventor: KATO EISAKU
IPC: G03C1/06
Filed: 1990-04-19
Abstract: PURPOSE:To improve the forming efficiency by incorporating a coupler which forms the aldehyde imparted with diffusion resistance as the group to be eliminated by reaction with the oxidant of a developer cleaves the protective group of a formyl group into the above photosensitive material. CONSTITUTION:The group to be eliminated by the reaction with the oxidant of the developer has the protective group of the formyl group and this photosensitive material has the coupler which forms the coupler imparted with the diffusion resistance as this protective group cleaves. The dye formed by the reaction is only formed imagewise as the cleavage reaction of the protective group of the formyl group takes place in succession to the reaction of the oxidant of the developer and the coupler and, therefore, the dye formed by the reaction of the aldehyde with the developer does not flow away into a processing bath. The dye of the two molecules imparted with the diffusion resistance is formed by the oxidation of the silver of two atoms from the coupler of one molecule. The color developing efficiency is improved in this way.

Title: Cpu monitor circuit
Inventor: TANABE JUNJI
IPC: G06F11/30
Filed: 1990-04-19
Abstract: PURPOSE:To decrease the number of watchdog timer circuits down to just one and to reduce the scale of a CPU monitor circuit by instructing a host CPU to exchange the normal data via a dual port RAM and also to always monitor the working of a slave CPU. CONSTITUTION:A host CPU 2 outputs periodically the clear signals to a decoder/latch circuit 4 through a bus (a) to clear the timer of a watchdog timer circuit 1. The circuit 4 decodes those clear signals and sends a timer clear signal (c) serving as a pulse signal to the circuit 1 to clear the timer. At the same time, the CPU 2 exchanges periodically the data to a slave CPU 5 via a dual port RAM 3 in order to monitor whether the working of the CPU 5 is correct or not. Thus the number of required circuits 1 is decreased down to just one and the scale of the circuit 1 is reduced.

Abstract: PURPOSE: To obtain the information of coordinate positions by detecting vibration waves.  
     CONSTITUTION: Piezo-electric element 2 for X-axis use and piezo-electric element 3 for Y-axis use, which are respectively sticked to the end portions of input board 1 consisting of isotropic media, are driven alternately by pulses generated from X- direction driving circuit 4 and Y-direction driving circuit 5 and, as the result, mechanical vibration is emitted to the input board. The coordinates (X,Y) of the pen position can be obtained by detecting the mechanical vibration by means of piezo- electric pen 7 and counting the time interval from the pulse driving to the detection. The signal converted to an electrical signal by piezo-electric element in piezo-electric pen 7 is amplified by amplifier 11, delayed by delay circuit 46 and the output of amplifier 11 with the output of delay circuit 46 is compared by comparator 47; when the level of the delay circuit 46 exceeds the level of amplifier 45, the comparator generates the compared output.
